Cleaning with less chemicals

[TeddyBare]

My new year's resolution this year is to be greener and I've decided I'd like to try cleaning without / with less chemicals. Please share your tips with me!
Are there any alternatives to washing up liquid?
What do you use to anti-bacterialise kitchen surfaces / to mop the floor with?
How do you clean the loo?

Citrus Magic products are a good alternative - no harmful substances, and they smell great too
They cost a bit more but last absolute ages.

Does anyone know where you can buy bicarbonate of soda in bulk other than the internet.
